Most small pul lstart engines have a compression release built in to the valves. You won't see any good compression until the RPM's build up the the release kicks off. IIRC, it's a little lever built into the exhaust valve/cam, so there is no way to bypass it w/o tearing apart the engine.
Never heard of E85 hurting rings - lots of engines use it with only minor changes in the fuel system. Like has been said before, it might have dissolved some crap in the fuel system and/or fuel filter and caused a blockage.
